Situated on the slopes of the still-active volcano Mount Hengill, on the edge of Thingvellir National Park and less than an hour outside Reykjavik, Ion Luxury Adventure Hotel is seriously in harmony with its environment. Energy and hot water is provided by the nearby Nesjavellir Geothermal Power Station and surrounding hot springs; locally sourced wood is utilized throughout the hotel's interiors, all furniture is made from from recycled materials, and images of Icelandic wildlife are displayed throughout.

The hotel also makes use of natural light through floor-to-ceiling windows in bedrooms and in its onsite Northern Lights bar, which juts out and overhangs the lava fields and from where, on dark, clear nights, you can watch the Aurora Borealis light up the sky.
